Y ANTIRATTLING DEVICE FOR AUTOMOBILE DOORS.

Application filed January 3, 1928. Serial No. 244,234.

The present invention relates to improvements in anti-rattling devices and has for its principal object to provide a ydevice for association with an automobile for the purpose of preventing any movement of the doors thereof after the same have been shut or closed, thereby eliminating all unnecessary noises.

One of the important objects of the present invention is to provide an automobile antirattling device of the above mentioned character which will at all times be positive and eiiicient in its operation, the same being further simple in construction, inexpensive, strong and durable and further well adapted to the purpose for'which it is designed.

A still further object of the invention is to provide an anti-rattling device of the above mentioned character that can be readily and easily installed without necessitating any material alterations of the parts of the door frame.

Other objects and advantages of the invention will become apparent from the following description when taken in' connection with the accompanying drawings.

/ In the accompanying part of the application: l n y Figure 1 is a top plan view' showing an automobile door in the act of being closed, and disclosing the normal position of the striker projection.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a front edge elevation of the anti rattling device embodying our invention showing the manner in which the same is set in the door frame.

Figure 4 is a side elevation of the antirattling device per se. r o

Figure 5 is a detail perspective view of one of the slidable boxings that is formed with a strike projection atits'forward edge.

Figure 6 is a detail perspectiveview of the plate that is secured on the free edge portion of an automobile door and which 1s provided with the usual laterally extending lug, and

Figure 7 is a detail perspective view of'one of the resilient blocks that is associated with each of the slidable boxings.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of our invent-ion, the numeral 1 designates a substantially trapezoidal shaped casing, one side of which is open and as is'clearly drawings forming illustrated in Figures 3 and 4 of the drawings, the forward edge of the casing is open. Flanges 2 and 3 respectively extend inwardly from the forward edge of the closed side of the casing and the inner opposed ends of these flanges are spaced with respect to each other for the purpose of providing a passage for the lug 4 that extends laterally from the rectangular plate 5, the latter being secured on the edge portion 6 of the swinging door of an automobile, which door is designated by the letter A. The door is provided with the usual lateral iaiige 7 along its outer free edge that will extend over the adjacent edge .portion of the door frame B.

This casing is set in a suitable recess formed in the edge portion of the door frame B, and a face plate 8 is secured on the edge of the door frame B to cover the open side ofthe casing 1 as is clearly disclosed in Figures 2 and 3 of the drawings. The recess 9 that is formed in the door frame to accommodate the casing is o f such size as to cause the forward edge portion of the casing to be disposed Hush with the outer face of thedoor frame.

The invention further comprehends the provision of a pair of opposed boxings 10 and 1l, respectively, that are adapted for slidable movement within the casing 1. Each boxing is open at its outer side and also at its adjacent and, the opposite end portion of the boxmg being so shaped as to cooperate withthe converging end portions ofthe trapezoidal shaped casing 1 4whereby a wedging action will be aifected in the manner to be presently described.

Striker projections 12 and 13 areformed on the forward edge portion of the boxings 10 and 11 respectively, and these projections extend for the full length of the forward edges of the boxings and are of such thickness as to be adapted for slidable movement between the free longitudinal edges of the flanges 2 and 3 formed on the 'closed side of the casing 1, and the face plate 8;

The striker projections 12 and 13 are so formed on the forward edges of the boxings as to provide the shoulders 14 and the flanges 2 and 3`cooperate with the shoulders of the respective boxings to limit the outward slid- 105 ing movement of said boxings.

A leaf spring 15 is secured at its intermediate portion to the rear wall of the casing 1' as at 16, the free ends of the leaf spring being curved reversely with respect to the curva- 11o e relation and furthermore project beyond the i boxings. The outer inner opposed edges of the open ends of the o posed ends of the rubber blocks are cut off at an'angle so as to properly engage the angularly disposed outer end portions of the boxings. In Figure 7 there is shown a detailed perspective view of one of these rubber blocks.

The rubber blocks 19 and -20 are normally held apart through the medium of the spring shown generally at 21. This spring consists lcooperate to provide a of an elongated fiat strip of spring metal that is bent intermediate lits ends to form a pair of parallel disposed arms 22 and 2 3, respectively', the free ends thereof being disosed outwardly in opposite directions as illustrated at24. and 25 with reference more particularly to Figure 4 and the laterally extending outer free end'sof these arms are dis osed between. the forward edges of the rub `er blocks and the inner faces of the rcspective forward edges of the boxin The resilient arms 22 and 23 furt ermore ide for the door lugs 4 and as is clearly s own in the drawings, the entrance between the arms is located in alinement with the space formed between the iianges 2 and 3. It will also be observed that the face plate 8 is cut out a't this articular point, the cut out portion exten ing from the outer'edge of the plate to a point.'

adjacent the opposite sides and the cut out portion is designated by the numeral 26 in i ure 2. f

noperation it will be observed that when the door A is moved to a closed position with respect to the door frame B the lu s 4 will ass between the sprin arms 22 an 23 and dueto the force'applie by the outer curved ends of the leaf s ring against the boxings 10 and 11, and urther due to the sha e ofthe ends of the housing, the rubber b ocks will exert an inward pressure on the spring arms y22 and 23 where y said arms will cooperate to grip the lugs and cause the door to be supported in a rigid manner against'vertical movement', and when the flange 7 of the door strikes the projections 12 and 13, the

boxings will be forcedk inwardly against the tension of the spring 15 and thus exert such pressure on thedoor as to prevent movement of thev door in a lateral direction.

In thisv manner the device will prevent any possibility of the door rattling, and thereby eliminate all unnecessary noises. Furthermore the anti-rattling means is of such construction as to permit the door to be readily and easily opened whenever necessar Also a device of the above mentioned c aracter canbe manufactured at a very low cost and can be furthermore readily and easily inf stalled without necessitating any lmaterial alterations of the door frame.

While we have shown the preferred embodiment of our invention, it is to be understood thatr minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit 'of the invention and the scope of the appended claims.
